| 摘 要：在汽车的行驶方面，它的制动系统会对汽车的安全可靠造成很大影响。由于道路的不断提速，车辆速度不断增大还有在路上车流量的逐步增长，汽车的制动系统对于汽车的安全性与可靠性有着极大的作用。汽车要是想要更好的变现出它优良的动力性能，就必须要保证它要有好的制动性能和可靠的制动系的工作。25729 盘式制动器还有另外一个名字叫做碟式制动器，它的构造简单、重量较轻、散热较快、便于调整，这是这种制动器的优势，在高负载的过程中对于它耐高温的性能表现的尤为突出，同样，它所取得的制动效果也是非常稳定的，在道路不平或者是在冬季行车，在短时间内盘式制动更容易停车。这次的设计主要是对汽车制动器的功能设计做要求，配分它的制动力，分析它的结构方案，选择制动器的重要零件以及选择最主要的参数，进行制动器相关的各种参数计算，同时分析装配好的尺寸链。在设计的过程中会涉及许多因素，如选择同步系数，计算制动力矩和选择制动器的主要元件等。在制动器设计的一般原则下，要总体的对制动效能进行充分的思考，还有制动效果是否稳定，调整制动的间隙是否简便，制动器的大小，重量以及噪音等各种成分来设计这个产品。 关键词 盘式制动器；制动系统；同步系数 毕业论文设计说明书外文摘要 Title Design of the braking system of disk brakes Abstract Automotive vehicle brake system directly affects the driving safety and parking reliability. With the rapid development of highway and the increased speed limit as well as the increasing traffic density, in order to ensure driving and parking safety, the reliability of automotive brake systems has become increasingly important. Only excellent reliable car braking system can fully play its role of adjusting the car’s dynamic performance. Disc brake, also known as dish brakes, it brakes and ventilates fast and is also light weight. Its simple structure, easy clearance adjustment, outstanding performance at high temperature with heavy load, better working stability enables it to stop the car quicker than traditional drum brakes at winter and bad road conditions. The function and design requirement of the vehicle brake system, analysis of the construction scheme, distribution of braking torque, selection of the main components as well as the main coefficient calculation of the system, are all concluded in this paper. Based on the primary principle of brake designing, taking the efficiency, stability, and easy clearance adjustment as well as the size, quality and noise making into consideration, this paper covers many aspects while designing.
